EXTENSION TABLE.

Application filed November 28, 1922. Serial 1 10. 603,818.

This invention relates to slides for extension tables and has for itsobject to provide a device of this character which will consist of fewparts, be inexpensive to manufact-ure and strong and durable inoperation.

A further object is to provide a table slide in which binding of theseveral parts due to warping will be reduced to a minimum.

A still further object of this invention is to provide a device of theabove mentioned character whose construction will be such that thetendency of the several parts to warp will be counteracted by thespecific structure of the device, thus reducing warping to a minimum.

Other objects and advantages of this invention will be apparent from thefollowing description, taken in conjunction with the accompanyingdrawings in which similar characters of reference denote similar partsin the several views.

In the drawings:

Figure 1 is fragmentary view of a table top showing the presentinvention applied thereto,

Fig. 2 is a side elevation of the device in partial extended position,showing the table top in section,

Fig. 3 shows perspective views of. the several parts of the invention,

Fig. 4 is an end view of the device,

Fig. 5 is a sectional view on the line 55 Fig. 4, and

Fig. 6 is a sectional view on the line 66 Fig. 4.

Referring more in detail to the drawings, the slide of the presentinvention comprises a base 1 side strips 2, and a central strip 3, allof substantially the same length.

The base 1 is provided in its upper surface with a longitudinal recess 4in which is rigidly secured the central strip 3, by means of screws 5 orthe like.

As shown more clearly in Fig. 4, the longitudinal faces of central strip3 are each provided with a longitudinal recess 6, which recesses arepreferably oppositely arranged. At one end of one of the recesses 6, isrigidly secured a stop 7, and at the opposite end of the'opposite recess6 is rigidly secured a stop 8, said stops 7 and 8 being provided withreduced ends 7 and 8 respectively.

These stops 7 and 8 serve to limit the relative movement of the sidestrips 2 as will now be described.

Side strips 2 are each provided with a longitudinal recess in one oftheir longitudinal faces, as designated by numeral 9, and with alongitudinal recess 10 in the lower faces thereof.

The recesses 9 are so arranged as to be positioned adjacent the recesses6 of the central strip 3 and the recesses 10 are so arranged as to bepositioned adjacent longitudinal recesses llformed in the base 1 on eachside of recess 4 and extending the full length of said base 1.

At each end of each recess 11 in base 1 is rigidly secured a stop 12provided with a reduced end 12 and loosely and slidably mounted withineach of the recesses 9 is a guide strip 13. Rigidly secured with one endof each recess 9 is a stop 14, and rigidly secured within each recess10, near one end thereof is a stop 15,,stops 14 and 15 each beingprovided with a reduced end.

Secured to side strips 2, as more clearlyshown in Figs. 1 and 2, as thetable top sections 15 and 16, as is usual in the. art.

With the parts in assembled position as shown in Fig. 4, to separate thetable top sections 16 and 17, the base 1, of the slide being rigidlysecured to the customary pedestal cap, it will be obvious, from aninspection of Fig. 5 that the side strips 2 will slide in oppositedirections upon the upper face of base 1, (the lower edges of section 2being supported by the upper face of base 1 as indicated at 18) untilstops 15 reach stops 14 which limit the movement of the severalsections. During this extension movement the side strips 2 will beguided by means of strips 13 within recesses 9, stops 8 and 14, alsolimiting the movement of the several parts of the device.

Because of the rigid connection of base 1 with central strip 3, it willbe pbvious that should either of these parts tend to warp the rigidconnections therebetween will serve to retain the parts in their normalpositions.

What I claim is:

A table slide comprising a base provided with a central longitudinalgroove throughout its length, a groove in said base on each side of saidcentral groove and extending tl'iroughout the length of the base, a stopill) in each end of the side grooves, a central strip rigidly secured inthe central groove of the base, and provided with longitudinallydisposed recesses extending throughout the length of said central strip,a stop in one end of each recess, side strips each having a runway onits inner side face extending throughout its length, stops at the endsof said runways, a guide strip slida- 10 bly mounted in the recesses ofthe central strip and extending into the runways of the side strips, agroove in the bottom face 01 each side strip registering with the sidegrooves of the base and a tongue in said grooves bridging the jointbetween the lower face of the side strips and the base.

In testimony whereof I afiix my signature.
